Some say it was a stroke due to a seizure. Granted, Carlson, 35, does have a history of seizures, but was this really the cause? I've know people with epilepsy - and have been in almost every possible environment with them (including very high-pressure/anxious moments or when they've had both 'petit mal' & 'grand mal' seizures) but I have never seen any of them speak gibberish like this! Very strange!
